Answer:
10000ha=1m²
=(1000m/1000)²
=1km²/1000²
1ha=1km²/1000² ×1/1000
8.6ha=8.6×1km²/1000² ×1/1000
Answer:
-87 (If I'm correct - sorry if I'm not)
Step-by-step explanation:
<u>substitute:</u>
4(3-6) - 3(-5)^2
<u>Parenthesize:</u>
4(-3) - 3(-5)^2
<u>Exponents:</u>
4(-3) - 3(25)
<u>Multiply:</u>
-12 - 75
<u>Subtract:</u>
-12 - 75 = -87
<u>ANSWER::::</u>
<u><em>-87</em></u>
Answer:
y = x + 3
Step-by-step explanation:
I'm assuming that you are asking for a line perpendicular to
3x + 3y = 3 and going through (-1, 2)
first find the slope of the line
3y = -3x + 3
y = -1x + 1, the slope is -1 so the perpendicular slope is 1
y = mx + b
2 = 1(-1) + b
3 = b
y = x + 3
